6 'Claims.

The invention relates to tops for stoves and more particularly to apressed steel top for a sheet metal heating stove.

An object of the invention is to produce a one- 5 piece pressed steelstove top having integral drawn collars therein for attachment of thefiring door and the stovepipe.

Another object is to provide a simple, inexpensive and easily attachedhinge for the firing 1O door. 7' A further object is the provision of alining to the outside and/ or inside of the stovepipe collar.

The above objects, together with others which will be apparent from thedrawings and follow- 15 ing description of which may be later pointedout may be attained by constructing the improved stove top in the mannerillustrated in the accompanying drawings, in which Figure 1 is a planview of the blank from whic 20 the improved stove top is made;

Fig. 7, a detached perspective view of the improved hinge before thesame is inserted into the door and collar; and

Fig. 8, a perspective view of a stove provided with the improved top.

Similar numerals refer to similar parts throughout the drawings.

The improved stove top to which the invention pertains is adapted foruse upon a sheet metal wood-burning heater, as indicated generally atI!) in Fig. 8. Stoves of this character are provided with a draftregulator as indicated at H, which may be located upon the body of thestove or upon a door l2 upon an ash pouch I3 as illustrated.

The top M is ordinarily flat and formed of sheet metal having a fuelopening surrounded by a collar l5 and covered by a firing door l6 and astovepipe collar "which in general practice are formed of separatepieces of metal attached to the top of the stove.

The present invention contemplates the provision of a drawn steel top,of heavier gauge than the remainder of the stove and having integralcollars surrounding the fuel opening and stovepipe opening.

In producing the improved stove top, the steel sheet from which the sameis to be made is first 5 normalized, after which the blank shown inFigs. 1 and 2 is stamped therefrom having the opening lfia ofconsiderably smaller diameter than the fuel opening collar to be formedat. this point and the opening I'm of considerably 10 less diameter thanthe stovepipe collar to be formed at this point, the opening Ha beingsurrounded by the spaced concentric rib iii of a diameter substantiallythe same as the finished g stovepipe collar to be formed.

The blank thus formed is then placed in suitable dies having means forengaging the rib 18 to prevent displacement of this portion of the blankduring the drawing operation and the stovepipe collar I! is drawn upwardin cylindric 20 form, as best shown in Fig. 3 and may be provided at itsupper edge with the rim bead [9. The fuel opening collar is drawn upwardand inclined as shownat 15 and then downturned and substantiallystraight as shown at 211. Slots 2| are formed in the inclined portion l5and sub stantially straight portion 20 of the fuel opening collar forattachment of the hinge for the firing door it, as will be laterdescribed.

It has been found by experience that in this deep drawing of thestovepipe collar H, the upper open end thereof is occasionally torn orsplit and in order to cover up this damaged upper end of the stovepipecollar so as to improve the looks as well as to reinforce the same, alining may be provided for the inside of the collar as shown in Fig. 4,this lining being formed of a strip 22 of light gauge sheet metal ofsuitable length and width which may be located within the collar I! asshown in Fig. 4, the lower edge of said strip being bent outward formingan angular flange 23 against the lower end of the collar I? and theupper edge of the strip 22 being beaded over the open upper edge of thecollar l1, covering and reinforcing the damaged portion thereof.

If desired, a lining may be provided upon the outside of the collar I!as shown in Fig. 5, in the form of a light gauge strip 25 whichsurrounds the collar, the bead 24 being formed over the upper edgethereof. This outer collar covers any imperfections which may extenddownward some distance from the upper edge of the collar IT.

The hinge provided for attaching the firing door l E to the collarsurrounding the fuel opening may be formed of a single piece of sheetmetal as shown in Fig. 7, the metal being bent substantially half-roundat a point spaced from one end, as indicated at 26, one end portion 27of the hinge being preferably of considerably less length than the otherend portion 28.

In order to attach the hinge, the ends 27 and 28 may be bent toward.each other with the fingers, the shorter end 2'! being inserted throughthe slot .29 located directly above the rim bead 29a of the door IS, thecurved portion 26 of the hinge being located around said rim bead. Thetwo ends 2'! and 28 may then be squeezed tightly together and insertedthrough the slots 2| in the the body of the stove. and reinforces theupper portion of the stove and fuel opening collar and bent downward asshown at 3'3 in Fig. 6, the terminal portion of the long end 28 thenbeing bent backward below the edge of the straight portion 2e of thecollar as indicated at 3 i. This forms a very simple, inexpensive andeasily attached hinge for hinging the firing door to the fuel openingcollar.

Another feature of the improved stove top is the formation of thedownwardly curved edge 32 having the recess 33 formed at its lower endand terminating in the flange 34 adapted to be seamed to the upper edgeof the side wall it forming This greatly strengthens slightly less depththan the collar and terminating just above the level of the stove top, afiring door arranged to seat around said tapered collar, and a hinge forthe firing door whereby the door is arranged to be swung upon ahorizontal pivot.

2. A sheet metal stove top having an integral, cylindric collar formedtherein for the attach- P ment of a Stovepipe, there being a fuelopening in said stove top and an integral collar surrounding saidopening, said collar being upwardly and slightly inwardly tapered andterminating in a downturned substantially cylindric flange of slightlyless depth than the collar and terminating just above the level of thestove top, a firing door arranged to seat around said tapered collar,and a hinge for'the firing door whereby the door is arranged to be swungupon a horizontal pivot.

3. A stove top having a fuel opening therein and a collar surroundingsaid opening and being upwardly and slightly inwardly tapered andterminating in a downturned flange, there being registering slotsthrough the upturned portion and downturned flange of said collar, afiring door for said opening having a flared lower edge portion arrangedto seat over said tapered collar and having a slot near its edge, and ahinge formed of a single strip of sheet metal bent upon itselfintermediate its ends and having one end portion located through theslot in the door and both ends located through the slots in the collarand bent angularly downward against said flange whereby the firing dooris arranged to: be

swung upon a horizontal pivot.

4. A sheet metal stove having a fuel opening therein and an integralcollar surrounding said opening and being upwardly and slightly inwardlytapered and terminating in a downturned flange of slightly less depththan the collar and terminating just above the level of the stove top, afiring door for said opening having a flared lower edge portion arrangedto seat over said tapered collar, and a hinge for the firing doorwhereby the door is arranged to be swung upon a horizontal pivot.

5. A sheet metal stove having a fuel opening therein and an integralcollar surrounding said opening and being upwardly and slightly inwardlytapered and terminating in a downturned and slightly inwardly taperedflange of slightly less depth than the collar and terminating just abovethe level of the stove top, a firing door arranged to seat around saidtapered collar, and a hinge for the firing door whereby the door isarranged to be swung upon a horizontal pivot. 6. A sheet metal stove tophaving its peripheral portion curved downward and outward and thenformed outward and upward forming a peripheral channel around the edgeportion of said stove top, and terminating in an angular attachingflange adapted to be downturned for connection to the body portion of astove.
